Oregon's bridges to be readied for the Big One
There are 2,671 bridges in Oregon’s highway system; researchers develop a computer model which, for the first time, gives state authorities bridge-by-bridge estimates of damage, repair cost, and traffic delay costs associated with a shattering western Oregon quake; the new tool would allow engineers to prioritize which of the state’s bridges should get seismic upgrades

Bay Area cities lag in making housing quake-safe
Many public buildings in Bay Area cities have been retrofitted to make them more earthquake-resistant; most of the two types of private homes which are especially vulnerable to damage by tremors — wood-frame, “soft-story” buildings and concrete-frame structures that lack sufficient steel reinforcement — have not yet been retrofitted

New Army Corps of Engineers' policy instructs project designers to take rising sea levels into account
The Army Corps will from now on incorporate estimates of rising sea levels in all its plans for flood control, navigation, and other water projects; the corps has had a planning policy for rising sea levels since 1986, but the instructions were less than a page long, buried in a 1,000-page document and largely ignored; the new policy is articulated in a 44-page stand-alone document

U.K. agency to increase flood protection
The number of properties in England and Wales at significant risk of flooding could increase from 570,000 in 2009 to over 900,000 by 2035 at current levels of flood-defense investment; the Environment Agency says it is planning for the long haul, saying it is already planning to manage a predicted 1 meter rise in sea levels, and a predicted 10 percent increase in wave heights and wind speeds, both of which will increase the threat from coastal surges

Army Corps of Engineers in a $1 billion project to protect New Orleans' flank
The West Bank area of New Orleans is primed for growth, but experts warn that developers and residents should be aware of a problem: the bowl-shaped area is considered by experts as perhaps the city’s most vulnerable flank;’

U.S. Congress holds hearings on geoengineering
Geoengineering — the effort to design systems which would change the world’s climate — was once a fringe phenomenon; it has been moving into the mainstream, though, as more and more scientists are growing increasingly concerned that, even if we commit to cutting emissions drastically, we have already waited too long, and that by the time we actually reduce emissions, enough greenhouse gases will have accumulated to cause serious climate disasters

Using technology to prepare vulnerable communities for earthquakes
Satellite photographs and remotely measured surface heights from NASA will be used for assessing the vulnerability of natural slopes to earthquake-induced landslides; a team of U.K. scientists will also build up a database of slopes that failed in earthquakes; the information collected will include local geology, vegetation, slope angle, distance from the fault, and the amount of ground shaking

African desert rift confirmed as new ocean is forming
Geologists show that seafloor dynamics are at work in splitting African continent; scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea

Earthquake-proof airport terminal in Istanbul airport
Large swaths of Turkey are earthquake prone; the 1999 Kocaeli earthquake, for example, killed 17,000 people, injured 50,000, and destroyed 27,000 buildings, leaving 500,000 homeless; estimates of property losses range from $3 billion to $6.5 billion; engineers claim they have made the terminal at Istanbul Sabiha Gokcen International Airport earthquake-proof

Louisiana levee to use stabilizing fabric
The 1,600-foot earthen levee, which runs south from the Old Estelle Pump Station, has failed twice, once in the early 1990s and again in 2007 when two sections totaling 600 feet long slumped badly; Army Corps of Engineers will use geotextile fabric to stabilize known trouble spots before raising the levee from 10 feet to 14.5 feet

Despite concerns, development still heads to the coast
Many scientists predict that by 2100, sea levels would rise more than one meter; still, Florida has opened more vulnerable areas along the Atlantic coast to construction — and has done so more than any other state

Aussies worry about rising sea levels
About 80 percent of Australians live in coastal areas, and a new parliamentary report recommends new laws banning further development in coastal regions

Cosmic entropy could be 100 times greater than previously thought
Entropy increases as the number of ways the system can be arranged microscopically without changing the external appearance increases; new study shows that cosmic entropy is a 100 times greater than earlier estimates; the entropy of the universe must be below the maximum theoretical value or life and other complex phenomena will cease to exist; as the entropy gradually increases it will eventually approach the theoretical maximum, a state many physicists have called the heat death of the universe; the new study thus shows that our universe is closer to its death than previously thought

Without water reform Asia will face food shortage by 2050
There are three options for meeting the food needs of Asia’s population, which will expand by one-and-a-half billion people over the next forty years: The first is to import large quantities of cereals from other regions; the second to improve and expand rainfed agriculture; and the third to focus on irrigated farmlands

Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Trump’s Cuts to Federal Wildfire Crews Could Have “Scary” Consequences
President Donald Trump’s moves to slash the federal workforce have gutted the ranks of wildland firefighters and support personnel, fire professionals warn, leaving communities to face deadly consequences when big blazes arrive this summer. States, tribes and fire chiefs are preparing for a fire season with minimal federal support.
